[U-Boot-Users] relocating from flash to ram on AT91RM9200DK

[David Peters]

I'm using a custom board that was based off of the AT91RM9200DK/EK.  Right
now we're booting from parallel flash using boot.bin (from Atmel), but I'd
like to get rid of the need for it.  I assume I can use
CONFIG_SKIP_RELOCATE_UBOOT and CONFIG_SKIP_LOWLEVEL_INIT to do this.

What do I need to set TEXT_BASE to for this to work?

This depends on your chosen memory map, i. e. base address  and  size
of your RAM and intended location of U-Boot in it.

Assuming I'm using the AT91RM9200DK, can you provide an example of a working
configuration.  Shouldn't the default configuration work with
CONFIG_SKIP_RELOCATE_UBOOT and CONFIG_SKIP_LOWLEVEL_INIT undefined?

Why don't you just look at the settings of all the  other  AT91RM9200
boards (including the AT91RM9200DK, which works fine as is)?
